Modulating Pressure Control Solenoid Valve

Position/Task/Design/Function

Component Illustration:

Position
In the shell of the electric valve control unit (Y3/6) and pressed against the shift plate by a spring.

Task
To control the modulating pressure depending on the continuously changing operating conditions, such as load and gear change.

Design
The modulating pressure regulating solenoid valve (Y3/6y1) has an interference fit and is sealed off to the valve body of the shift plate (2a) by a seal (arrow). The contact springs (32) at the solenoid valve engage in a slot in the conductor tracks (33). The force of the contact springs (32) ensures secure contacts.

Function
The modulating pressure regulating solenoid valve (Y3/6y1) assigns a proportional pressure to the current which is controlled by the ETC control module (N15/3) according to the load.
